Vistagy Survey Benchmarks Composites Best-Practices

Do you harbor any curiosity as to where peers or other industry leaders stand on domain knowledge and expertise around composite design and manufacturing?

A recent survey conducted by Vistagy attempts to provide an industry benchmark, so companies can gauge where they stand compared with their peers and uncover best-practices that can improve their performance. The survey, based on responses from 140 participants across multiple industries (most prominently in aerospace, automotive, and wind energy), found that use of composite materials is on the rise across sectors. However, a solid 44 percent of responding companies still need to enhance their knowledge of the composite manufacturing process if they want to improve their competitiveness.

"Even as composites extend further and further into industry, there's a general lack of maturity in the processes, as well as overall knowledgeable composites domain expertise in general," Bruce Boes, Vistagy's vice president of product management and marketing, told me. "Even though composites are very widely used in aerospace and have branched out into some other industries, it's still relatively new."

The use of composite materials in design and manufacturing may still be emerging, but it's definitely growing for a number of reasons. The average company responding to the Vistagy survey had 360 engineers on site, with about 10 percent of them actively engaged in composite design. Forty percent of the companies were designing a significant share of their parts (75 percent) in composites, while 30 percent of companies designed less than 25 percent of their parts in the new materials. The remaining 30 percent were somewhere in between.

The primary goals for companies designing with composites were varied. Eighty-one percent were on a mission to reduce weight, 69 percent sought to improve strength-to-weight ratios, 51 percent were attempting to combine multiple parts, 25 percent looked to extend product life, and 31 percent were striving to lower maintenance costs.

One of the key findings of the survey was that many companies (34 percent) are still in the early stages of composite use and are just working to turn metal parts into composites at a 1:1 ratio as part of a weight reduction strategy for the final product.

Best-in-class companies are well beyond this stage. According to the survey results, they are combining six or more parts into one, and 10 percent actually combine 10 or more parts. They are reducing maintenance costs and improving quality by as much as 30 percent by taking advantage of the inherent material properties of composites. And they are reducing weight by 30 percent or more, with 34 percent of respondents claiming they are beating their weight reduction goals.

Best-in-class performers were also the most mature in terms of creating processes around composite design and manufacturing, as well as integrating key technology tools such as specialty analysis software. For example, to achieve target costs, best-in-class performers were investing in simulation tools and other resources, instead of focusing solely on swapping metal parts with composites.

Wind blade design companies, in particular, stood out in the survey results. These designers were more apt than companies in other sectors to design for maintainability and decreased maintenance, and they were more likely to apply analysis techniques and software early in the design process. In fact, the wind energy industry starts with FEA analysis 45 percent of the time, compared to 39 percent for companies in other sectors.

Vistagy's Boes says this is a primary factor in why this sector is out in front with best-in-class results. "A lot of this has to do with what they are designing," he explains. "It's incredibly expensive to maintain offshore blades. You can't really have a failure, because the cost of replacing them can blow the budget."

Vistagy's survey shone the spotlight on a number of key trends surrounding composite design and manufacturing. For me, however, one of the stand outs was the fact that best-in-class performers have typically put new processes in place to support and promote the use of composites. Given that the survey didn't drill down into those specific best practices, I'm curious as to what kind of new processes engineering organizations are adopting in order to better leverage composites and achieve gains beyond part cost reduction. Any one out there care to weigh in?

@Akmose98: Thanks for the feedback. Nice, practical suggestions for those getting started with composite design. Can I ask what industry you're in and what type of applications you've worked on involving composites?

I'm now an independent consultant for materials and processes, having worked in the field of large composite structures , solid rocket motors, rocket launchers,etc, for about 29 years. I have authored or edited three books on composites, Filament Winding, Composite Structure Fabrication, Composite filament Winding, Handbook of Composites, 2ond ed.

Virtual Reality (VR) headsets are getting ready to explode onto the market and it appears all the heavy tech companies are trying to out-develop one another with better features than their competition. Fledgling start-up Vrvana has joined the fray.

A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.

While every company might have their own solution for PLM, Aras Innovator 10 intends to make PLM easier for all company sizes through its customization. The program is also not resource intensive, which allows it to be appropriated for any use. Some have even linked it to the Raspberry Pi.

solidThinking updated its Inspire program with a multitude of features to expedite the conception and prototype process. The latest version lets users blend design with engineering and manufacturing constraints to produce the cheapest, most efficient design before production.
